摘要：

Anomeric O-arylation and O-hetarylation of tetra-O-benzyl-, tetra-O-acetyl-, and O-unprotected glucose (la-c) can be directly performed with electron deficient aromatic and heteroaromatic systems having fluoro- (2A-2F) or phenylsulfonyl (3B, 3G-3K), respectively, as leaving groups, The reactions were carried out in DMF as solvent at room temperature with NaH as the base; they led in the products 4 to an exchange of the leaving group by the glucopyranosyloxy moiety; mainly beta-products were obtained.
